利用xmlhttp根据网址调用接口获取数据 //引入com组件中的microsoft.xml.3.0
代码
using MSXML2;
public void GetCon(String Url) { string vs = string.empty; try { XMLHTTP XmlHttp = new MSXML2.XMLHTTPClass(); XmlHttp.open("get", url, false, null, null); XmlHttp.send(null); if (XmlHttp.readyState == 4) { vs = XmlHttp.responseText; } } catch (Exception ex) { throw new exception(ex.Message); }
利用xmlhttp下载
using MSXML2;
public void GetDown(String Url) { string StringFileName = Url.Substring(Url.LastIndexOf("/") + 1); string StringFilePath = Request.PhysicalApplicationPath; if (!StringFilePath.EndsWith("/")) StringFilePath += "/"; MSXML2.XMLHTTP _xmlhttp = new MSXML2.XMLHTTPClass(); _xmlhttp.open("GET", Url, false, null, null); _xmlhttp.send(""); if (_xmlhttp.readyState == 4) { if (System.IO.File.Exists(StringFilePath + StringFileName)) System.IO.File.Delete(StringFilePath + StringFileName); System.IO.FileStream fs = new System.IO.FileStream(StringFilePath + StringFileName, System.IO.FileMode.CreateNew); System.IO.BinaryWriter w = new System.IO.BinaryWriter(fs); w.Write((byte[])_xmlhttp.responseBody); w.Close(); fs.Close(); Response.Write("文件已经得到。<br><a href='" + Request.ApplicationPath + StringFileName + "' target='_blank'>"); Response.Write("查看" + StringFileName + "</a>"); } else Response.Write(_xmlhttp.statusText); Response.End();
